So i'm running a dedicated 470 with my 590 and all the games i play im not really sure if its actually being utilized. With afterburner OSD it sits there as GPU3 at 51 mhz and like 100mhz on the memory. I never see the % go up in any game(Crysis, warhead, Crysis 2, BFBC2, etc) Is this normal? I've got it set in the control panel with the check box checked for dedicated to physx.
